Abstract: 1,273,659. Press feed mechanisms; metal strip feeds. DIAMOND DIE & MOLD CO. 30 July, 1970 [8 Sept., 1969], No. 36976/70. Headings B3Q and B3W. A feed mechanism for a machine tool, e.g. a press, including a tool slide 14, comprises a feed slide 24, a timing piston and cylinder device 76, 66, a loading piston and cylinder device 62, 60 and passages 68, 72 connecting the cylinders. A latch arm 44 holds the slide 24 during an operating stroke of the slide 14, and as the latter moves upwardly after completing its operating stroke an arm 56 engages the latch arm to release the slide. Springs 42 move the slide 24 to feed a component 20 to the work station by a feed dog 26 at a rate determined by the flow of fluid through the passage 72. The speed of the stroke may be varied by a cam (110) engaging a spring loaded needle valve (100) to provide a smooth acceleration and deceleration of the feed slide, Fig. 7 (not shown) and the stroke of the slide is adjusted by nuts 90, 92. On the next downward stroke and near the end thereof, the tool slide 14 engages the piston 62 to return the feed slide 24.

Title: A process and apparatus for the prevention of a deposit of fur in the granulation of dust-like substances
IPC: B08B9/087
Filed: 1954-12-23
Abstract: <PICT:0777869/III/1> A rotating drum 1 for granulating carbon black &c. has mounted concentrically within it a wire basket 12 which is of slightly smaller diameter and is rotated at a greater or smaller speed than the drum to prevent a deposit forming on the walls of the drum. The basket is mounted on a shaft 11, and has a conveyer 19 on its inside wall.  Powdered material is fed into the drum 1 by a worm conveyer 6, is conveyed through the drum by the conveyer 19, and the pellets formed during transition are expelled through slot 7. The wire basket may be positively driven or not and in the latter event the necessary rotation is obtained by friction with the deposit on the drum walls.

[Also in Division G3] In an automatic edge guiding system for a moving web, means detecting lateral movement of the web control an intermittently operating motor moving coupled ends of two guide rolls so that they are pivoted about their other ends to correct the lateral position of the web. In Fig. 2, an endless belt 10, e.g. for conveying corrugated paperboard, passes over a roller 11 and under a parallel roller 12. At one side the rollers are mounted in bearers 21 which are rotatable about fixed vertical axes, and at the other side the rollers are mounted in bearers 23 which are rotatable about vertical axes on a member 27 which is movable longitudinally by a fluid-pressure servomotor 16.

Abstract: 1,255,119. Spindle drive. HAMEL G.m.b.H. 5 Aug., 1970 [11 Sept., 1969], No. 37772/70. Heading DID. A spindle 22 which is mounted so as to be pivoted into and out of engagement with a driving belt is mounted on a pivoted arm 18, the spindle axis being parallel to the pivoting axis. A resilient member (spring 26, Fig. 1) urges the pivoted arm into a working position with the spindle wharve contacting the driving belt, as shown in Fig. 2. A securing device 12, 52 is arranged to secure the spindle in this working position and in a neutral position with the spindle wharve spaced from the driving belt. The securing device comprises an apertured plate 12 and at least one contact piece 42 which can move around the inside face of the aperture. The contact piece 42 is carried on a stop member 32 which is rotatable between two end positions, and can be held in at least one thereof by an overcentre device 52, the two end positions corresponding to the working and neutral positions of the spindle. As shown, when it is required to disengage the spindle from the drive belt the operator turns handle 58 to the left of Fig. 2, against the pressure of overcentre device 52 so that roller 42 emerges from the notch 56 and eventually roller 42' enters notch 56' thereby disengaging the spindle. The overcentre device 52 retains the spindle in this position.

Title: Substituted phenyl aryl ketones
IPC: C07D243/24
Filed: 1964-05-26
Abstract: The invention comprises o-[2-(acyloxy or hydroxy) acylamino]-phenyl aryl ketones, especially of formula <FORM:1021382/C2/1> wherein ring A may be substituted by 1 or 2 Cl or Br atoms, NO2, C1- 6-alkyl (optionally halogenated) or alkylsulphonyl groups, R, R1 and R2 are H, alkyl, aryl or aralkyl, Ar is aryl and R3 is acyloxy or hydroxy. The acyloxy group may be derived from a carboxylic or a sulphonic acid.  Such compounds are prepared by reacting an o-aminophenyl aryl ketone with the appropriate acyloxyacyl halide, anhydride or acid, followed by hydrolysis of the acyloxy to the hydroxy group, if desired.  Alternative routes are (a) where the acyloxy group is carboxylic, reacting an o-(2-iodoacetamido)-phenyl aryl ketone with an alkali metal carboxylate; (b) where the acyloxy group is sulphonic, obtaining the corresponding carboxylic acyloxy compound by the general method, hydrolysing off the acyl group and reacting the hydroxy-acylamino compound so obtained with a sulphonyl halide, anhydride or acid.  In specified compounds, 2-acetamido-5-chlorobenzophenone is substituted on the side-chain (C) by acetoxy, hydroxy, p-bromophenylsulphonoxy, p-toluene-sulphonoxy, methylsulphonoxy or phenylsulphonoxy.

Title: Removal of sulphur from illuminating, coke-oven and like gases
IPC: C10K1/00
Filed: 1929-12-24
Abstract: A process for purifying illuminating or cokeoven gas by converting the sulphur into sulphur dioxide by passage of the gas at a temperature of about 300-400 DEG  C. over a catalyst such as nickel oxide, and combining the sulphur dioxide with sufficient alkali, preferably ammonia, to form mainly neutral alkali sulphite, or to form a sulphite which is subsequently converted to a mainly neutral alkali sulphite, is characterized by heating the alkali sulphite in solution under pressure, for instance, at 200-300 DEG  C., to form alkali sulphate and sulphide.  Any thiosulphate or bisulphite formed is also decomposed.  Catalysts such as selenium, tellurium or heavy metal oxides may be added. In the case where ammonium sulphite is decomposed, ammonium sulphate may subsequently be salted out or crystallized from the filtered liquor after removal of ammonia and hydrogen sulphide by boiling or blowing in steam.  The ammonia and hydrogen sulphide may be added to the gas to be purified preferably prior to the catalyst.  Alternatively, when the sulphur content of the gas is sufficiently high, they may be passed to the ammonia distiller for the recovery of ammonia, which is added alone to the gas to be purified, the hydrogen sulphide being voided.  Water may be p  condensed from the gas before oxidation and the ammonia and hydrogen sulphide subsequently expelled therefrom and returned to the oxidizer.  Examples relate to the absorption of the gases in water, ammonium sulphite solution, when ammonium bisulphate is formed and subsequently treated with ammonia to produce the sulphite, and in a solution of sodium sulphite when sodium bisulphite is produced. Sodium carbonate is added, the resulting sulphite converted as above and sodium sulphate crystallized. Sodium sulphide remains dissolved. Vessels of aluminium or chromium steel such as V2A may conveniently be used.
